Abstract:

An existing pressure correction method to model unsteady flow with arbitrarily moving boundaries has been adapted to simulate the interaction of three-dimensional blood flow with a mitral valve in an anatomically-correct contractile thin-walled left heart. This noniterative method, which is first-order time accurate, solves the three-dimensional unsteady Navier-Stokes equations with arbitrarily moving boundaries for the no slip boundary condition. It is capable of realistically modeling the blood-valve interaction, since it allows the simulation of both passive tissue (i. e., heart valves) and active tissue (i. e., heart muscle fibers).
